LaSalle-Peru Township High School is a comprehensive high school composed of grades 9-12 with an enrollment of approximately 1,300 students. The school operates on a fixed daily schedule of seven periods of 50 or 55 minutes each. Two semesters of 18 weeks make up the school year with summer school optional. The school is accredited by the North Central Association and the State of Illinois.
Since being formed in the late 19th century, LaSalle-Peru Township High School has served as a center of learning for generations of Illinois Valley residents. The main campus building was constructed in 1926 as part of a campus expansion to address the growing Illinois Valley community. Built in a gothic-style, the school building with its stately clock tower looking down upon LaSalle and one-of-a-kind auditorium, has stood the tests of time to become an architectural landmark within the community. The LP campus, which straddles the border of LaSalle and Peru, has grown over the years to feature additional buildings for vocational learning programs, a recently completed sports complex, and a Great Depression-era football stadium that continues to awe visitors nearly 80 years later.
Part of the LP High School mission is to motivate students to develop the abilities to think critically, solve problems and communicate effectively. To accomplish this goal, the School District offers a wide variety of classes, clubs and organizations, and sports and a wonderful array of exciting, challenging, and interesting classes across nine academic divisions, including many honors, Advanced Placement (AP), and dual credit opportunities. These academic and extracurricular activities prepare LP students for life after high school, whether they plan to continue their education at the collegiate level or go straight to the workforce.
